Stress analysis on the interference connection based on finite element method

针对传统理论计算分析方法仅适用于外廓简单配合零件的局限,利用有限元法模拟了轴毂过盈配合分析过程,分析结果与传统理论分析结果具有较好的一致性。在此基础上,对某机构复杂轴毂配合情况进行了有限元法计算,该方法为复杂外廓零件的过盈配合计算提供了有力的依据。研究成果为校核连接零件强度、计算传动能力提供了依据,从而能更好地利用过盈配合的结构形式为机械设计服务。

The traditional calculation method is only suitable for simple assembly parts. It uses finite element method to simulate interference connection, the simulation result is consistent to traditional calculation. Taking a shaft part of complex institution as example, it realizes the finite element simulation. The result is rational. This method provides the forceful basis for irregular outline interference connection analysis.
